"...after a break for "Nothing Compares 2 U" and, uh, Sarah McLachlan's "Angel", Prince finally picked up his guitar. The hits were all his: "Raspberry Beret" and "Cream" to name two. But there was also a spirited rendition and interpolation of Michael Jackson's "Don't Stop 'til You Get Enough", a nice hit to rip into once you've sort of gotten tired of singing your own. Then came the opening notes of "Purple Rain" and a curious declaration: "I don't need to be here, but I want to be here.""
